Shell thin, vitreous, composed of 4 larval whorls and 2,3 inflated postlarval whorls, very convex in outlines with a deep suture. No distinct subsutural sinus zone. Adult shell with regular spiral furrows. On the first whorl there is a faint sinuous axial sculpture, rapidly disappearing when the shell grows older. Larval shell with bent axial ribs and short spiral riblets between them. Outer lip regularly convex. Siphonal canal very short. Columellar side slightly sinuous, forming a gentle angle where it meets the body whorl. Colour of the larval shell brown. Colour of the adult shell yellowish white turning into light brown when the animal grows older.
Dimensions: height of the shell 6.52 mm, breadth 4.12 mm; height of the aperture 3.67 mm, breadth 2.02 mm. This species is easily recognizable by the colour and sculpture of the adult shell. The general appearance is a little like that of Pleurotomella lottae, but among the characters that species has a subsutural sinus zone, very broad protoconch and much flatter whorls.
